Research on design of ice-making system for skating rink of Capital Indoor Stadium

This paper presents the reconstruction process of the ice-making system for the skating rink of the Capital Indoor Stadium, analyses the cooling load composition of the ice-making system, and calculates the cooling load under different ice surface temperatures and initial freezing time. On this basis, the heat exchange way of the ice-making system is determined, the ice-making system is established, and the performance requirements for all components of the system are defined. At the same time, the circulation process of the ice-making system is analysed and the state parameters of the ice-making cycle are calculated by taking the energy consumption ratio as the index. After the operation test in 2022 Olympic Winter Games, the design suitability and innovation of the ice-making system are verified, providing a technical support for the successful hosting of the Olympic Winter Games.
